My invention relates to liquid fuel .sprayn ers for furnaces and moreespecially to that type of such sprayers in which the fuel is suppliedupon a slightly inclined wall or pan and then sprayed at the interiorfront edge of this pan or wall by the action of a steam jet passingthrough a slit arranged beneath the said edge and parallel to the same.

The main object of the said invention is to provide means for heatingthe oil to be sprayed to such a degree that also very thick oil may beeasily and finely sprayed by the action of the steam jet.

The invention consists essentially in providing near and around thesteam conduit of the sprayer several passages or conduits for the fueland to lead the oil to be sprayed successively through all the saidpassages or conduits, so that the same is successfully heated by thesteam used for spraying purposes.

rlhe proposed invention is hereinafter described with reference to theaccompanying drawing, on which- Figure 1 is a longitudinal section ofthe device; Fig. 2 is an end view of the spraying device; Fig. 3 is asection taken on the line A-B of Fig. 1; and Fig. 4 is a section takenon the line E-F of Fig. 1. l
